Silk, second traction fiber are fixedly connected through the armrest seat and seat pocket posterior joint with the preceding lock tongue；Pull the unlock
During knob, the unlock knob drives the preceding lock tongue intra-articular movement before the seat pocket by second traction fiber, makes
The preceding lock tongue be retracted to before the seat pocket it is intra-articular with will the preceding lock tongue unlock, while the rear end inclined-plane of the preceding lock tongue supports
It presses the inclined-plane of the lock tongue slanted kicking block and the unlock head cover is driven to move out.It is equipped with and is used for and vehicle in the seat pocket posterior joint
The rear lock tongue 14 of the recoil backing plate locking of frame and for lock tongue after lock tongue to be made to pop up the rear lock of the cushion posterior joint lateral surface
Tongue spring.
Wherein, the preceding joint of the cushion and cushion posterior joint partly overlapping and be rotatablely connected by shaft, and the seat
Pad the outside that preceding joint is arranged on the cushion posterior joint.The cushion rod is equipped with leg tube 15, before the armrest seat is equipped with
Handrail 16, the cushion posterior joint are equipped with preceding fluffy bar 17, cover board are respectively equipped on the preceding joint of the cushion and cushion posterior joint
18.It is equipped with upper lock tongue spring fixed seat in the backing tube, the inner end of the upper lock tongue spring is fixed on the upper lock tongue spring and is consolidated
In reservation, outer end is fixedly connected with the upper lock tongue, and first traction fiber sequentially passes through the upper lock tongue spring and upper lock tongue
Spring fixed seat enters in backing tube.The upper side that the one gear tooth 91 and two keeps off tooth 92 is arc-shaped curved surface, and downside is
It faces directly.The preceding lock tongue is equipped with traction fiber fixing groove 111, and the front elevational sectional of the preceding lock tongue is triangle, and has chamfering,
The rear end of the preceding lock tongue has an oblique sliding surface 112.The lower end section of the upper lock tongue is triangle, and with chamfering.It is described
The lower end of backing tube be circular mounting head, the circular mounting head center be equipped with backing tube shaft, the two of the backing tube shaft
End is rotatably positioned in the cushion posterior joint.The armrest seat is equipped with limited post 41, behind the preceding joint of the cushion and cushion
Intra-articular to be respectively equipped with limiting slot 42, the both ends of the limited post are respectively placed in the limit of the preceding joint of the cushion and cushion posterior joint
In the slot of position.The unlock head cover includes the circular cover for being located at outside and the top for being fixed on the circular cover medial surface surrounding
Pawl, the end outward bending of the top pawl are simultaneously pushed against on the lateral surface of the slanted kicking block.
The children trolley sits pocket fold mechanism when in use, it is locked respectively by two preceding lock tongues in the preceding seat of vehicle frame
Backing plate both sides, lock tongue locks respectively in the both sides of the recoil backing plate of vehicle frame, while between the front and rear seating pad of vehicle frame after two
In lock tongue spring column insertion unlock head cover, pocket both sides will be sat and locked respectively by three positions, formed after locking with vehicle frame
One, firm stable.
Use sit pocket when, if desired for backing tube is adjusted backward, such as from the sitting state of seat pocket be adjusted to semi-lying state or
When adjusting from semi-lying state to lying status, hand pinches upper lock tongue knob 6, and upper lock tongue 7, upper lock tongue 7 are pulled by the first traction fiber
It squeezes upper lock tongue spring and is retracted in backing tube, so that upper lock tongue unlocks, backing tube rotating backward can carry out at this time
Gear is adjusted.When needing forward to adjust backing tube, such as adjust to semi-lying state from lying status or adjusted from semi-lying state
During to sitting state, it is only necessary to backing tube is promoted forward, because the shelves tooth upper side of backing tube is arranged to arcwall face, downside
Face is to face directly, therefore when backing tube promotes forward, upper lock tongue is made to be slided on the arcwall face of shelves tooth and compress upper lock tongue spring,
And upper lock tongue is finally made to slip into next gear.
During if you need to which pocket and vehicle frame dismounting will be sat, pulling unlock knob 13, before unlock shakes hands 13 by the drive of the second traction fiber
Lock tongue 11 moves backward, and preceding lock tongue is retracted unlock out of preceding seating pad of the vehicle frame, while preceding lock tongue 11 moves backward, at it tiltedly
Slanted kicking block 10 is jacked up under the action of sliding surface, slanted kicking block 10 forces unlock head cover 12 to move out, will when unlock head cover moves out
Bounce tongue lock column on vehicle frame is ejected out of cushion posterior joint, so as to sit pocket unlock, can will be sat pocket at this time and be disassembled from vehicle frame.
When pocket is sat in installation, the recoil backing plate locking of the rear lock tongue insertion vehicle frame on seat pocket posterior joint is fixed, while vehicle frame two
Bounce tongue lock column 100 between seating pad squeezes unlock head cover, and stretches into intra-articular locking before seat pocket, and unlock head cover squeezes oblique simultaneously
Jacking block, make slanted kicking block be entirely retracted to sit pocket before it is intra-articular, at this time sit the preceding joint of pocket and sit pocket posterior joint it is in the unlocked state, preceding lock
Tongue is protruding under the action of the spring, and preceding lock tongue stretches into locking in the preceding seating pad of vehicle frame.
When vehicle frame folding, sit pocket can be folded with vehicle frame, the preceding seating pad of vehicle frame forward and recoil pad backward
It turns folding respectively, and drives to sit the preceding joint of pocket and sit pocket posterior joint and be turned out folding respectively, sit the convex of the preceding joint of pocket at this time
Race pushes the tooth boss of backrest gear teeth, and backrest gear teeth squeezes gear teeth resetting spring and to close to seat pocket posterior joint direction
Movement, so that the upper lock tongue of backing tube slips into the arc neutral gear area of backrest gear teeth, backing tube can freely swing at this time, lean on
Penstock unlocks, and folds under gravity, armrest seat also folds under gravity.
When seat pocket is folded with vehicle frame, sit the rotation axis that the preceding joint of pocket is connected with seat pocket posterior joint rotating around it and mutually turn
Dynamic, the limited post of armrest seat both sides is located in its limiting slot respectively, and limiting slot drives limited post to rotate, when vehicle frame is opened completely
When, armrest seat is also for normal operating condition.
In addition, the children trolley is sat in pocket fold mechanism, sitting pocket front and rear can exchange placement.It sits pocket and exchanges placement, be convenient for
When carrying out, mother can be face-to-face with baby, and baby sees mother at any time, and baby's mood can be pacified at any time by also allowing for mother.
It can be seen that the children trolley sit pocket fold mechanism by sit the preceding joint of pocket and sit pocket posterior joint on preceding lock tongue and
Lock tongue and the corresponding bounce tongue lock column of unlock head cover form corresponding 3 locking structures in the left and right sides with vehicle frame respectively afterwards, 3 points
The triangular structure that locking structure is formed is more solid and reliable, can not only be connected with vehicle frame, but also can be shaken hands by unlocking
It can be achieved with sitting 3 locking structures unlock of pocket, there are simple for structure, simple operation and other advantages.Simultaneously sit pocket can realize it is flat
Lie, semi-lying and three kinds of gears of sitting are switched fast, adjust, it is necessary to realized by upper lock tongue knob when adjusting gear backward,
Can prevent maloperation, more securely and reliably, and forward regulation stall when, it is only necessary to forward promote backing tube can be realized, it is non-
Normal convenient and hommization.
